Overview
The AZ23B33-G3-18 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a surface-mount SOT-23 package. It provides two independent Zener diodes sharing a single anode terminal. The nominal Zener voltage is 33 V with a tight tolerance of ±2%. Electrical testing is conducted at a test current of 2 mA. The device supports a maximum power dissipation of 500 mW and operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- Tight voltage tolerance of ±2% for precision regulation applications
- High ESD protection capability exceeding 8 kV via human body model
Applications
- Precision voltage reference circuits requiring dual channels
- Overvoltage protection stages in signal conditioning paths
- Clamping networks in high-speed digital interfaces
Procurement Notes
Verify the specific suffix 'G3-18' against official documentation to confirm the 10,000-unit reel packaging format. Ensure compliance requirements match the base product number AZ23B33-G3 specifications before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel solution with strict ±2% voltage accuracy is required. Verify that the 2 mA test current aligns with the target application's biasing constraints. Confirm thermal management capabilities meet the 500 mW absolute maximum rating under expected operating conditions.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series utilizes silicon planar technology and offers various voltage grades according to the E24 standard. The 'B' designation specifically indicates the tighter ±2% tolerance variant compared to the standard ±5% 'C' grade.
